VENDING DEVICE.

Application filed January 20, 1908.

To all whom it may concern:

Be it known that I, ARTHUR PESTEL, a subject of the Emperor of Germany, and resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Vending Devices, of which the fol lowing is a specification.

My invention relates to devices for vending electricity or other forces or commodities, and has for its object to provide a device of this character. the operation of which will be simple and reliable.

In the accompanying drawings I have illustrated three forms of my invention, intended for the sale of electricity.

Figure l is an elevation of the complete apparatus, with the casing in section on line 11 of Fig. 2; Fig. 2 is a horizontal section on line 22 of Fig. 1; Fig. 3 is a cross section on line 3-3 of Fig. 1; Fig. 4 is a detail elevation of a portion of the mechanism, with parts in section; Fig. 5 is a similar view showing a difierent construction of the same parts; Fig. 6 is a partial view of a form of my invention for vending a certain amount of electricity, instead of selling electricity during a predetermined time, as in the first formof my invention; Fig. 7 is a sectional detail, taken on line 77 of Fig. 1; Figs. 8 and 9 show two positions of a lever which forms part of the structure represented in Figs. 1 to 4 and 7; and Fig. 10 is a perspective view of the coin guide and coin support.

A designates a base board to which is secured (by screws or otherwise) the casing or cover B which normally conceals most of the apparatus. From the casing projects the operating handle C which is secured removably (as by a screw D) to a rod E which forms part of a slide F suitably guided on the frame. A spring Gr tends to keep the slide in its inner position, but this spring may be omitted. The outward movement of the slide F is limited by the engagement of its head F with a stop formed by the head H of a screw H adjustable in a stationary support. A graduation F may be provided on the slide F, to indicate, in connection with a stationary edge A the length of time Specification of Letters Patent.

that the device will run before stopping. It will be understood that these adjustments are made by a mechanic, with the cover B removed, but when the cover is in position, the adjustment cannot be changed. To hold the screw'after adjustment, I may provide a spring H fitting int-o notches of the screw head H.

The slide F has a coin chute F adapted to register, in the position of rest, with an opening I in a stationary guide I and also with the coin-slot B of the cover B. The coin J rests temporarily in a stationary forked holder having prongs I and against a shoulder K of a slide K. When the slide F is pulled outward, the coin, by its engagement with said shoulder, pulls the slide K outward to the same extent. As long as no coin is inserted, the movement of the slide F will not affect the slide K. When the slide F comes against the stop H, and is then pushed back either by hand or by the spring Gr, the coin being no longer supported by the prongs I nor held by pressure against the shoulder K, drops into the chute L, L, leading to the coin receptacle M. The slide K may be provided with a pivoted projection K adapted to operate the arm N of a counter or register N at each outward movement of said slide, thus showing how many times the apparatus has been operated. The counter may be of the same construction as a cyclometer.

The slide K has an extension K with a guideway K in which is movable a pin or roller 0 upon an arm O mounted loosely on the shaft 0 The arm 0 carries a springpressed pawl O engaging the teeth of a ratchet wheel P which is kept from turning in one direction, by means of a pawl P fulcrumed on the frame. wheel P is secured rigidly to the shaft 0 as is also a toothed wheel P and the inner end of the drive spring or main spring Q, the outer end of which is secured to the gear Q. This gear has a suitable connection with an escapement. Thus in the particular construction shown, the gear Q meshes with a lantern pinion R on a shaft R carrying also a larger gear R the gear R meshes with the pinion S on the shaft S carrying The ratchet also the gear S the latter meshes with a pinion T on the shaft T of the escapement wheel T operated by means of an anchor U and pins V from a balance wheel V which swings in the usual way under the influence of a. hair-spring V The toothed wheel P meshes with a pinion rigid on a shaft lV which rotates in suitable bearings, but cannot slide lengthwise. On this shaft is mounted loosely so as to be capable of turning, but not sliding, a pinion X meshing with the gear Q and provided wit-h a cam surface X. On this cam surface is adapted to ride an anti-friction ball Y carried by a shift member Y which is compelled to turn with the shaft V, but can slide lengthwise thereof; for instance, the shaft may have a slit through which is driven a pin Y on the shift member. Into an annular groove Y of the shift member Y projects a roller Z at the end of a lever Z secured to a rock shaft Z and pressed downward by spring Z On the shaft Z is secured rigidly an arm Z engaging a pin a on a switch lever a which is mounted on said shaft loosely. The lever a carries switch-operating members (a which in the raised position of the lever close electric circuits by forcing the movable switch tongues 6 into contact wit-h the relatively stationary switch-tongues Z). lVith the lever a is connected a finger a which in the lowered position of the lever is in the path of the balance wheel V so as to stop it. The lever (b is further provided with a pin a the shape of which is shown best in Figs. 8 and 9. Adjacent to this pin a sleeve 0 is fulcrumed in a stationary bracket, said sleeve having a projection 0 with a recess 0 A spring (Z tends to turn the sleeve in the direction indicated by the arrow. lVhen the lever a is in its normal position, its pin (4* lies against a fiat surface of the projection c, at one side of the recess 0 (Fig. 8). Vhen the lever a is moved (Fig. 9), as soon as the pin a clears said flat surface, the sleeve 0 turns under the influence of the spring (Z so that the pin a is received in the recess 0 thus locking the lever to in its operative position. The sleeve 0 is connected rigidly with an arm 0 against which rests the end 6 of a lever e secured rigidly to the rock shaft Z. The arm Z is also engaged by a pin f projected from a lever f loosely mounted on the shaft Z and pressed by a spring f. The end f of this lever is normally in line with an opening F in the slide head F, but when the shaft Z is rocked so as to press against the pin 7', the end f is moved into the path of the slide head F, preventing it from being returned to its original position until the lever f resumes the position shown in Fig. 3; the purpose of this arrangement is to prevent the insertion of additional coins until the mechanism has operated the full length of time, since the slide F closes the coin opening 1 except when the slide is in its original position.

The operation is as follows: The coin J inserted through the slot 13 and opening I is received between the prongs I and rests on them, immediately in the rear of the shoulder K of the slide K, the upper part of the coin being contained in the chute F (see Figs. 7 and 10). The slide F is then pulled outward by means of the handle C. Owing to the engagement of the coin J with the shoulder K, the slide K shares this outward movement, which is limited by the engagement of the slide head F with the screw head H. The forward movement of the slide F brings its head F in front of or beyond the lever f. The forward movement of the slide K operates the counter N and also, by means of the arm 0 and pawl 0 turns the ratchet wheel P so as to wind the spring Q. The turning of the ratchet wheel P and ofthe shaft 0 also rotates the gear wheel P (Fig. and the shaft to an extent corresponding to the movement of the slide K. The wheel X and cam X remain stationary, but the shift member Y is 1'0- tated with the shaft and as the ball Y rides on the cam surface X, the shift member Y is moved lengthwise of the shaft, away from the wheel X. The normal position of the ball Y is near the step or shoulder of the cam X, shown at the left in Fig. 3. The longitudinal movement of the shift member Y rocks the lever Z, and the shaft Z. The arm Z by its engagement with the pin 7 swings the lever f into such a position that its enc f will be in the path of the slide head F, so that the lat ter cannot be moved back fully to its original position and will keep the coin opening I closed. The arm Z further, by its engagement with the pin a, swings the lever a into its operative position, closing the electric circuits at b, 7) and removing the finger a from the path of the balance wheel V, so that the clockwork is released. At the same time, the lever 6 has allowed the spring (Z to swing the sleeve 0 into the position (F 9) in which its projection 0 looks the lever a. The shaft V and ratchet P remain stationary while the clock work is running. The running of the clock work causes the wheel X to be rotated in such a direction as to cause the ball Y to slide down the cam X, as it were, that is, to allow the shift member Y to move toward the wheel X, under the influence of the spring Z Then the parts finally resume their original position, with the ball Y close to the shoulder or step of the cam X, the lever 0, being connected rigidly with the rock shaft Z, presses against the arm 0 and turns the sleeve 0 against the tension of the spring cZ so as to release the lever 64 from the projection 0. The clockwork is still running, but when the lever a is released as described, it moves back to its original position, either by gravity or under the influence of a spring (not shown) and thus breaks the electric circuits at Z), Z) and stops the clockwork by interposing the finger a) in the path of the balance .wheel V. The arm f is also returned to its original po sition, thus allowing the slide F to return to its original position in which the coin chute F 3 registers with the opening I.

It will be obvious that the time the clockwork will run, depends on the travel of the slide K, which is determined by the adjustment of the stop H. The return movement of the slide K is effected by the engagement of the head F with the forward end of said slide, see Fig. 1. After the coin J leaves the prongs I it is held simply by the forward pressure against the shoulder K, and the moment this pressure stops, the coin is released and falls on the chute L.

In the form of my invention described above, the shift member Y and the cam wheel X can be given only one complete revolution. In cases where a greater range of adjustment is desired, I may employ the structure shown in Fig. 5. The shift member 3/ is connected with the shaft in the same manner as before, by means of a pin passing through the slot l' but instead of having a ball Y, the shift member has a helical groove or cam groove y into which projects a pin 50 on the wheel 00 which as before can turn on the shaft 7 but cannot slide thereon. WVith this construction, more than a complete revolution can be given to the shift member, and the main spring Q may even be given several successive windings, without awaiting the running down of the clockwork, if the stop lever f is omitted.

In some cases it may not be desired to have the operation coin-controlled; it would then be sutlicient to connect the slides F and K permanently, as by passing a screw through the head F into the forward end of the slide K. Every outward movement of the handle C would then wind the spring Q and the counter N would register the number of operations as before, so that an inspector could be sent from time to time to note the number registered and prepare a bill accordingly.

So far as above described, it has been assumed that the apparatus is to run a predetermined length of time, say, five minutes or ten minutes, as the case may be. It may, however, be preferred in some cases to have the apparatus run until a predetermined amount of the force or commodity vended has been delivered. Fig. 6 shows how this can be done for the sale of electricity. The electric circuit would contain a watt-hour meter of any suitable construction, and this meter would be constructed to periodically send a current through the coils of an electromagnet 9, say once for every revolution of the meter shaft. The armature h, controlled by a spring it would be secured to the anchor at engaging the escapement. wheel T The balance wheel V and the finger a would be omitted, but otherwise the construction would be the same as shown in Fig. 1. It will be obvious that in this case the apparatus will run, not a predetermined length of time, but a predetermined number of revolutions of the meter, or in other words, until a predetermined amount of electricity has been delivered.
